I'm currently on 12.1.1 and got a notification of a pending update when I entered my car at 8:30am.
I scheduled it for 9am, but when I looked at my Tesla app a few minutes after 9am, it still said that the software updated is "Scheduled for Friday 9:00am".
So I went ahead and started the update from my phone. A few minutes later, I opened the app again and it said "Scheduled for Friday 9:07am" under the software update section.
If I tap that again, it prompts me to install it again..
Any idea what could be going on?
